It was 16 October, 1968. Smith had just won gold, and Carlos had won bronze in a 200-metre sprint at the Summer Olympics in Mexico City.
Smith and Carlos carefully planned intricate details of their protest together. Before stepping out, they each removed a running shoe to protest poverty in the US. In black socks, they made their way across the stadium grass to the stand. They walked slowly with hands clasped behind their backs as if in mourning, each holding their running shoe.
